Flight Controls Flashcards
How many laws are there
3 laws
Who changes the law
It is auto reconfigured
What are the 2 flight control computers
The Primary and Secondary, or PRIMs and SECs
Of the 5 computers, only 1 can
Safely control the airplane and land
PRIM 1 is normally
The master and sends info to the other 4 computers
If the green hyd is lost
PRIM 2 replaces PRIM 1 as the master computer
If all PRIMs fails, the SECs
Control all the surfaces in direct law
If all PRIMs fails
Each SECs operates as it’s own master
Yaw for turn coordination is
Indirectly controlled by the movement of the sidestick
In normal law, movement of the sidestick is
Regarded by the PRIMs as request
In normal law, the rudder
Has no protection like the sidestick input
What are the only 2 flight control that can operate with a complete loss of electrical power
The stabilizer and the rudder
The rudder has
A BCM that is self powered
All flight controls are powered by
Hydraulic power
How many ailerons
2 per wing
How many spoilers
6 per wing
The outboard ailerons are
Faired (inhibited) aboive 190 kt
Spoilers 2 to 6 also functions has
Roll augmentation
Is there an aileron trim
No
How many Flight Control pb switch
6
The 3 PRIMs receive inputs from
The ADIRU, SFCC, FMGC, LGCIU, accelerometers and rate gyros
There is a mechanical THS link via
The trim hand wheels
The SECs receive inputs from
The ADIRU, SFCC and LGCIU
The SECs do not receive input from what flight control
The speedbrake lever
The SECs cannot control
The THS
The inboard ailerons configuration allows for
4 computers to provide controls
The inputs to the hydaulic motor to control the THS are provided by
3 electric motors, 1 master, then 2, then 3
The elevator jack are operated by PRIM 1, then
PRIM 2, then SEC 1 and then SEC 2 in that order
If you pitch or roll, when the sidestick is released
The position will be maintained
A re-trim is not necesary for
A change in airspeed
The normal law prevents
Pitch and roll to go outside the normal flight envelope
In flight all spoiler panel can be used as
Speedbrake
How do you arm the ground spoilers
By lifting the spoilers handle
The sidestick position indicator only appears
On the ground
On the ECAM F/CTL page, the hyd normally shows green, what is the other color
Amber if low pressure
When a faulty spoiler panel is deflected when it shoudn’t, it shows as
An amber arrow
When a faulty spoiler panel is not deflected when it shoud, it shows as
It’s position number in amber and underlined
There is __ slats and __ flaps per wing
7 and 2
There is __ SFCC each having __ channel for slats and __ channel for flaps
2, 1 and 1
What are the flaps positions
0, 1, 2, 3 and Full
How many reconfiguration laws are there, including the sub levels
5 reconfiguration laws
In Alt 1, the high speed and low energy protection are lost but replaced with
High/low speed stability
The low speed stability in Alt 1 does
Gently lower the nose if a low speed (5-10 kt before stall) is detected
The A-FLOOR feature of A/THR is ____ in Alt 1
Innoperative
The high speed stability in Alt 1 does
Pull the nose up to prevent an overspeed
Can you override the higl/low speed stability protections
Yes
Is pitch control the same in Alt 1 and Alt 2
Yes
In Alt 2, what is the normal roll rate
20 to 25 degrees per second
What spoilers are inhibited in Alt 2
Spoiler 2, 3 and 6
Does Dutch Roll damping remain available on Alt 2
Yes
In Alt 2, there is
No bank angle protection
In Alt 2, if 3 ADRs fails
The Alt 1 high speed stability fails
In Alt 2, if 2 ADRs fails
The Alt 1 low speed stability fails
In direct law, pitch and roll are
Directly controlled
In direct law, the auto trim of the THS is lost but
You can manually trim
You keep ___ and ____ in direct law
Stall warning and overspeed warning
In direct law, all protections are
Lost
If a MAN PITCH TRIM ONLY in red is displayed, it means
That both L and R elevator are at fault, the THS auto trim is disabled
When normal law is not available
The overspeed protection symbol (2 lines) is not displayed
When normal law is not available, the VàPROT and VàMAX are replaced by
Vsw indications
When bank angle protection is not available
The bank angle limits indicatior is replaced by an amber X
When Pitch Angle Protection is not available
The pitch angle limit indicator is replaced by an amber X
